The clinical values of acetoacetate ( AcAA ) and β hydroxybutyrate ( βHBA ) determination in classification of type 1 and2 diabetes were explored. 102 normal control subjects,33 cases of type 1 diabetes, and 104cases of type 2 diabetes were enrolled. Serum AcAA, βHBA, fasting plasma glucose ( FPG), C-peptide, and insulin levels were measured. The results showed that serum AcAA, βHBA, total ketone tody (TKB) levels in the diabetic groups were significantly higher than those of the normal group( P＜0. 01 ). AcAA, βHBA, TKB levels in type 1diabetes were higher as compared with those of type 2 diabetes( P＜0.01 ). The AcAA, βHBA, and TKB levels were negatively related with C-peptide and insulin in diabetic patients( P＜0. 01 ). All the type 1 diabetic patient were found to have TKB and lower C-peptide levels. TKB positive and lower C-peptide in type 2 diabetes were found in 47% and 26% respectively. Receiver operating characteristic (ROC) curve suggested that the area under the ROC curve of type 1 and type 2 diabetes was 0.926. The optimal operating point of the total ketone body was 0. 532 mmol/L with higher sensitivity and specificity. Enzymatic determination of acetoacetate and β hydroxybutyrate seems to have important clinical values for classification of type 1 and 2 diabetes.

The development of health-related quality of life (HRQL) instrument in traditional Chinese medicine (TCM) is increasing rapidly in China, but few studies focus on their necessity. This study explores the necessity of the development of TCM instruments from both theoretical and practice perspectives, and aims to explain whether the adoption of the cross-medical style is valid. Through theoretical analysis, both TCM and Western medicine instruments show the same objectives, whereas TCM instruments are more suitable for the Chinese social behavior, customs and expectations. In practical analysis, 47 TCM instruments were identified, among which 17 had 18 corresponding Western medical instruments. In the domains layer, except for physiological, psychological and social factors, TCM instruments focus more on the harmony between body and spirit, humanity and nature or human and society and the constitution, etc. In the facts layer, TCM instruments focus on the emotions, initiative social intercourse, TCM symptoms, diet, sleep, taste, feces and urine, etc. In addition, significant differences existed in the methods of information selection. There is no need to modify cross-medical style research except when TCM characteristic terms exist, but attention must be paid to the influence of culture in different areas. Therefore, the TCM instruments can resolve the limitations of the application of Western medical instruments to the Chinese setting, while also having remarkable abilities of information coverage and detection. Both forms of instruments have the capacity and requirement to inter-communicate with each other in order to serve the whole Chinese cultural system. Generally speaking, there is no need to modify the instruments in cross-medical style research. But this point requires further demonstration in the rigorous designed clinical trials.

Methods Stroke patients (64 cases) were selected from Yuetan community as the rehabilitation group by objective sampling based on inclusive and exclusive standard and 64 stroke patients wre selected from other community in Xicheng district as the control group. At the same time, 16 doctors and nurses from 10 clinics of Yuetan community health service center were trained and they gave reha-bilitative intervention to the rehabilitation group. After intervention for 6 months, the effect of rehabilitative in-tervention was evaluated compared with the control group who did not receive rehabilitative intervention. Re-suits The Fugl-Meyer score of the rehabilitation group was (76.14±12.48), the score of the control group was (19.36±14.32),which had significant difference compared with the rehabilitation group, P < 0.05. The Batthel index of the rehabilitation group was (72.25±10.22), the index of the control group was (22.62±9.71),which was significantly different from that of the rehabilitation group, P < 0.05.Besidcs, the rate of knowing health knowledge and healthy exercise in the rehabilitation group was higher than that of the control group, P < 0.05. Condusions The rehabilitation information net and systemic community rehabilitation intervention can im-prove the motor ability and the ability of daily activity for patients with stroke.

Objective The effect of different doses of ethylnitrosourea(ENU)and cyclophosphamide(CP)on the loss rate of CD59 on peripheral blood erythrocytes was explored to optimize the detection method of Pig-a gene mutation. Methods According to the weight and loss rate of CD59 on peripheral blood erythrocytes,rats were divided into 4 groups:the control group,CP 40 mg/kg group,ENU 10 mg/kg group and ENU 40 mg/kg group(n=6). The control group was injected i.p. with PBS,other groups were injected i.p. with corresponding solutions. The body weight of rats on days 0,7,14,21, 28, 42 and 56 were recorded. At the same time, blood samples were collected and incubated with antibodies,and the loss rate of RBCCD59-was detected by flow cytometry. Results Compared with the control group, at different time points, the body weight and weight gain of ENU 10 mg/kg group and ENU 40 mg/kg group had no statistically significant difference(P > 0.05),while those in the CP 40 mg/kg group were significantly decreased(P <0.05). The loss rate of RBCCD59-was significantly increased in the CP 40 mg/kg group at 28,42 and 56 days, ENU 10 mg/kg group at 42 and 56 days,and ENU 40 mg/kg group at 7,14,21,28,42 and 56 days,(P < 0.05). The results showed a dose-response relationship. Conclusions Under the conditions of this Pig-a mutation detection method,ENU is superior to CP on raising loss rate of RBCCD59-,ENU 40 mg/kg is better than 10 mg/kg,and 28 days is suitable as the test period.
